Design for obtaining the half-axial projection.

A device for obtaining the half-axial projection complementing single plane cine equipment is described. The design enables a single technician to raise and lower the patient's upper half of the body between 0 degrees and 20 degrees of longitudinal deviation from the rotating cradle, set between 0 degrees and 70 degrees of horizontal deviation. Materials cost less than $100 and can be assembled by personnel in most hospitals.

Optimizing cinefilm.

A system for improving the quality of cinefilm and for maintaining quality control is described. Objective criteria for contrast, resolution, and grain structure were established to measure the effects of varying X-ray dose, f-stop, development temperature, and selection of film and developer. We found that all variables nust be adjusted to maximize the viewing quality and that similar denisty curves can be achieved, independently of the choice of film and developer.
